Hassium (Hs) — 10-Year Trends

As of 2026-09-25 · the last 10 years

Hassium’s research intensity has fallen to about 10% of its own all-time peak, a level reached after a steady decline from 23% in 2016.

Research intensity ran from about 23% of the element's own all-time peak in 2016 to about 10% in 2026 — a steady decline, and the all-time peak (2009) lies before this window. Over the same span its share of research attention across all elements fell. Among the 118 elements, hassium has one of the smaller research literatures of any element.

The number of papers involving the element rose from about 15 in 2016 to about 22 in 2025 (1.47x). That is slower than the literature as a whole grew over the same years, so the element lost ground in the wider body of research even as its own count rose.

The research landscape is dominated by a single community: Superheavy Nuclei, Heavy-Ion Collisions, and Nuclear Structure. Hassium is a minor presence in this much larger community, with under 1% of its papers involving hassium. However, this community now accounts for 100% of hassium's recent research, a rising share from 62.5% in the previous period. Key work includes "Validating Vacuum Chromatography with Subsecond Radioisotopes of Hg for Superheavy Element Chemistry" (2026, cited once) and "Vacuum Chromatography of Tl on SiO₂ at the Single-Atom Level" (2016, cited about 33 times).

Three other communities—Lanthanide and Actinide Coordination Chemistry, an unnamed group, and Laser-Controlled Atomic Systems—have seen their share of hassium research decline to zero. This consolidation shows a narrowing of focus toward the element's core nuclear and superheavy element chemistry, while peripheral applications have receded.
